    Abstract: A multiple location dimming system may include a smart dimmer (e.g., a main load control device) and one or more remote dimmers (e.g., accessory devices) for controlling the amount of power delivered to a lighting load. The multiple location dimming system may be installed in place of a multiple location switch system (e.g., having three, four, or more multi-way switches), and may not require a neutral connection at any of the control devices of the multiple location dimming system. The main load control device and the accessory devices of the multiple location dimming system may be configured to display a present intensity level of a lighting load on one or more visual indicators. The accessory devices may have the same or different user interfaces as the main load control device, and may provide additional functionality over that which the main load control device offers.

    Abstract: Systems and methods are disclosed for using one or more gateway systems for integrating multiple load control systems running multiple versions of software such that the load control systems may appear to a user and be controlled by the user as a unified load control system. Gateways that manage or have managed the same resource may be organized into a Gateway Group. Gateway Groups names may be used for prefix attachment to facilitate routing. For example, a Composite Gateway may receive a request associated with a resource from a user. The Composite Gateway may determine which Gateway actively manages that resource and/or is the Gateway is a member of a Gateway Group. The composite Gateway may then apply one or more policies to facilitate the request. For example, if the Composite Gateway receives an information request, it may apply an authorization policy, a routing policy, and/or an aggregation policy.

    Abstract: A load control system may include control-target devices, control-source devices, and a system controller. The control-target devices may enter an association mode to associate with control-source devices. The control-target device may receive an identifier from the control-source device and store the identifier in memory when the control-target device to associate the control-target device and the control-source device. The system controller may retrieve the association information from the control-target device after integration into the load control system. The system controller may receive association information that is defined using other association procedures, such as an association procedure performed on a network device and uploaded to the system controller. The system controller may maintain the association information defined using the different association procedures after the system controller is integrated into the load control system. The system controller may also maintain control configuration information configured prior to integration of the system controller.

    Abstract: A load controller in a load control system may communicate messages with load control devices for controlling electrical loads. The load controller may receive messages that comprise values for controlling different load control parameters over different overlapping fade times. The load controller may identify a shorter remaining fade time for controlling one of the load control parameters and may determine an updated target value for controlling another load control parameter over the shorter remaining fade time. The load controller may transmit a series of messages within a limited fade time using an updated target value for each message to control an electrical load at a fade rate that during a fade time that is longer than the limited fade time.

    Abstract: A load regulation device is adapted to control an electrical load. The load regulation device may be in a low power state, a ready state, and/or an on state. The low power state is characterized by the electrical load being unenergized. The ready state is characterized by a load control device and/or the load regulation device using more power than the low power state and the electrical load being unenergized. The on state is characterized by the electrical load being energized. The load regulation device is configured to receive an indication of a user's presence when the load regulation device is in the low power state. The load regulation device is configured to change from the low power state to the ready state in response to receiving the indication. The load regulation device is configured to wait in the ready state for a change state instruction.

    Abstract: A control device configured for use in a load control system to control an electrical load external to the control device may comprise an actuation member having a front surface defining a capacitive touch surface configured to detect a touch actuation along at least a portion of the front surface. The control device includes a main printed circuit board (PCB) comprising a control circuit, a tactile switch, a controllably conductive device, and a drive circuit operatively coupled to a control input of the controllably conductive device for rendering the controllably conductive device conductive or non-conductive to control the amount of power delivered to the electrical load. The control device also includes a capacitive touch PCB that comprises a touch sensitive circuit comprising one or more receiving capacitive touch pads located on the capacitive touch PCB and arranged in a linear array adjacent to the capacitive touch surface.

    Abstract: A controllable lighting device may utilize a controllable impedance circuit to conduct a load current through an LED light source. The controllable impedance circuit may be coupled in series with a first switching device, which may be rendered conductive and non-conductive via a pulse-width modulated signal to adjust an average magnitude of the load current. The controllable lighting device may further comprise a control loop circuit that includes a second switching device. The second switching device may be rendered conductive and non-conductive in coordination with the first switching device to control when a feedback signal is provided to the control loop circuit and used to control the LED light source. The control loop circuit may be characterized by a time constant that is significantly greater than an operating period of the load current.

    Abstract: A load control device may be used to control and deliver power to an electrical load. The load control device may comprise a control circuit for controlling the power delivered to the electrical load. The load control device may comprise multiple actuators, where each of the actuators is connected between a terminal of the control circuit and a current regulating device. The number of the actuators may be greater than the number of the terminals. The control circuit may measure signals at the terminals and determine a state configuration for the actuators based on the measured signals. The control circuit may compare the state configuration to a predetermined dataset to detect a ghosting condition.
